Definitions

  • the invention relates to a brake disc according to the preamble of claim 1.
  • the state of the art is the DE 197 26 674 A1 , the DE 198 07 184 C1 , the DE 197 51 522 C1 and the DE 195 44 559 C1 called.
  • intermediate elements for torque and force transmission are provided by the cam of the hub on the support elements of the disc in these brake discs, which can be fastened for example by bolts to the cam of the hub.
  • the cams of the hub engage in the intermediate elements and on the other hand, the intermediate elements in the support elements, so that a secure torque transmission is ensured by the brake disc to the hub in both directions of rotation.
  • WO-A-02/087901 shows a brake disc with hub according to the preamble of claim 1.
  • the brake disc of DE 195 44 559 C1 has proven itself, but desirable is a further optimized cooling of the hub area.
  • the disc portion is provided with axially extending Abstweilstegen extending to the area in which the brake disc sits on the pot-like portion and serve as the cams, which engage between the support members of the brake disc and secure it on the hub in the circumferential direction wherein the AbstNeillstege radially within the brake disc or within the brake disc ring not or only via narrow connecting webs are radially connected to the outer periphery of the pot-like portion, in the latter case preferably such that results in a side view of a T-shape of the AbstNeillstege with the connecting webs, so that radially inward to the AbstNeillstegen and the support elements flow channels train for air.
  • the invention significantly improves the cooling of the hub brake disk, since it allows an increased supply of air into the hub region. It also reduces the heat conduction from the brake disc through the cams in the inner hub area.
  • the preferred selected axial fixation is particularly inexpensive and usually easy to assemble and disassemble.
  • Fig. 1 and 2 show a disc / hub connection with a brake disc 1, a disc and / or wheel hub 2, a plurality of intermediate elements 3 and securing elements. 4
  • ventilated brake disc of Fig. 1 has two friction rings 5, 6, which are connected to one another via connecting webs 7. On the inner circumference of the brake disc 1 supporting elements 8 are formed, which protrude substantially trapezoidal from the inner periphery of the friction rings 5, 6 inwardly. While driving a cooling air supply takes place between the support elements 8 in the air gap 9 between the friction rings 5.6.
  • the wheel hub 2 of Fig. 1 and 2 consists of a cup-shaped, hollow cylindrical portion 10 which merges at one of its axial ends in a flange or ring-like, radially from the pot portion 10 outwardly extending disc portion 11, on the outer circumference bores 12 are distributed for (not shown here) wheel bolts.
  • the disc portion 11 is provided with axially extending to the disc portion 11 supporting webs 13 which extend into the region in which the brake disc 1 sits on the cup-shaped portion 10.
  • the end portions of the Abstützstege 13 serve as cams 19 which engage between the support members 8 of the brake disc 1 and secure it on the hub in the circumferential direction or set to transmit a torque between the hub 2 and the brake disc 1.
  • the intermediate elements 3 are distributed, which are formed in a preferred embodiment as a U-shaped wire bracket.
  • the wire bracket 3 sit in the groove 14.
  • the elements 4 secure the brake disc position by means of screws 16 to the vehicle interior and braced at the same time on their spring action, the brake disc against projections on the wire hanger (see FIG. 6 showing the wire hanger 6 and the elements 4).
  • the support webs 13 Due to the fact that the support webs 13 have a substantially constant or even enlarging cross section over their entire length as far as the disk section 11, all or at least the essential forces are introduced directly into the disk section 11 during braking.
